Our interdependence can be a source of strength, but only if we agree to look beyond our immediate line of sight, only if we learn how to see our neighbors.
And the objectives for education overall need to be as specific as a video game so that those who are enrolled have a clear line of sight to where they're headed.
The upshot is that something hidden from an observer's line of sight might nevertheless be visible if it is sufficiently near a wall which can serve as a reflecting surface.
With limited line of sight beyond the few metres illuminated by the truck-sized submersible's onboard lights, navigating at this depth is a challenging task, making it easy to become disoriented on the seabed.
